Summary:
|
A quantum network is expected to enable enhanced applications by leveraging fundamental principles of quantum mechanics—such as entanglement, superposition, and the no-cloning theorem—which are not achievable using classical (non-quantum) networks, including conventional digital networks.
This Supplement aims to identify technical considerations for quantum networks, including relevant components and their configurations. It also introduces potential migration scenarios from Quantum Key Distribution Network (QKDN) towards quantum network. Furthermore, it outlines a standardization roadmap within ITU-T.
NOTE 1 – ITU-T Supplement 75 “ITU-T Y.3000 series – Quantum key distribution networks – Quantum-enabled future networks” has been published. This Supplement 75 focuses on the activity status of studies and research from academia, research institute, and standard development organizations (SDOs). However, this supplement introduces more technical aspects which might be required towards quantum network.
